GEARING.

Specification of Letters Patent.

Patented Jan. 24., 1911.

To all whom 'it may concern:

Be it known that I, WILLIAM L. HAYNns, a citizen of the United States, residing at Cynwyd, county of Montgomery, and State of Pennsylvania, have invented a new and useful Improvementin Gearing, of which the following is a full, clear,` and exact description, reference being had to the accompanying drawings, which form a part of this specification.

. My invention relates to the same class of tools and is for substantially the same purpose as that described in Letters Patent No. 915,856, issued to me March 23rd, 1909.

Specifically, the invention relates to a construction, different from, and in some respects an improvement upon, the construction illustrated and described in the aforesaid patent, for the purpose of providing a rapid traverse movement in either direction, as well as the slow feeding motion, and to insure the disengagement or severance of the slow feeding motion while the rapid traverse movement is in operation, and to insure the engagement of the slow feeding motion except when positively held out of action.

I will first describe the embodiment of my invention illustrated in the accompanying drawings and then point out the invention in the claims.

In the drawings: Figure 1 is a side elevation of my device. Fig. 2 is a plan view, part of the rail being shown in section. Fig. 3 is a sectional plan view on the line 3*?) of Fig. 1. Figs. f1 and 5 are sections on the line 1-L1 of Fig. 1, and clearly illustrates the operation of the various clutches embodied in my invention. Fig. 6 is a detail showing the means for shifting the positive clutch.

1 is a pulley carried at the top of one of the housings of the mill. 2 is a larger pulley carried at or near the bottom of the housing. The belt 120 connects these pulleys, passing under the pulley and over the pulley 41 so that these pulleys are driven in opposite directions as indicated by the arrows. The pulley 3 is loosely mounted on the sleeve The pulley 4t is loosely mounted on the sleeve 6. The sleeve 5 surrounds the shaft 7 and the sleeve 6 surrounds the shaft 8, both shafts being free to rotate in the respective sleeves.

Splined upon the shaft 7 is a clutch member 9, and splined upon the shaft 8 is a clutch member 10. The other or corresponding clutch member in each case is carried respectively by the pulleys 3 and 4:. When either clutch member 9 or l0 is engaged with its corresponding pulley, either the shaft 7 or the shaft 8 will revolve, but, as before described, the shafts will revolve in opposite directions.

On the end of the shaft 7 is a pinion 11 'and on the end of the shaft 8 is a pinion 19., so that wheitthese shafts revolve the pinions revolve. These two pinions engage with a wheel 13 mounted on the hub of a pinion 141. The pinion 1&1 is keyed to the feed screw or feed rod driving shaft 15. On the other end of this shaft 15 is a clutch member 16 engaging with a spiral gear 17, which meshes with a corresponding spiral gear 18 carried upon the feed shaft 19. IVhen the clutch surfaces 16 and 17 are engaged, the motion of the feed shaft 19 will be transmitted through the spiral gears and the clutch 16 to the shaft 15, and, by appropriate mechamsm, the rotation of shaft 15 is transmitted to the feed rod and the feed screw.

As may be seen, and as stated before, when the clutch surfaces 16 and 17 are engaged, the feed screw or feed rod is given a slow feeding movement from the feed shaft 19. If, however, the clutch surfaces 16 and 17 be disengaged and either the clutch 9 or 10 en gaged with its corresponding pulley, the shaft 15 will, dependent upon whether the clutch 9 or clutch 10 is in action, revolve in one direction or the other and at the speed produced by the belt and pulleys, before described, by which the rapid traverse motion may be transmitted in either direction to the feed screw or feed rod.

The mechanism by which I move into ac* tion the desired clutch member 9 or 10, and sin'iultaneously therewith disengage the clutch surfaces 16 and 17, is as follows: The clutch surfaces 16 and 17 are normally held in engagement with each other by the rods 44 and 15, provided with heads against which bear the springs 46 and 417. The other ends of these rods 14 and 15 are connected to the yoke 13, and the action of the springs is such that the yoke is drawn toward the spiral gear, and the clutch teeth brought into engagement so that the clutch surfaces 16 and 17 are normally connected. T he clutch members 9 and 10 are connected to a. frame 24C by, respectively, the yokes 35 and 36. The frame Q4 is mounted on the shaft 28.v From opposite ends of this frame 24 extend the links 29 and 30. The link 30 is connected by the lever 31 and links 32, with the bell crank 33 and handle 34.

37 are levers connected to link 29 and having a jaw portion 38, one surrounding one pin 39 and the other the other pin 39 on the yoke 43. Corresponding levers 40 are operatively connected with the lever 31. lVhen the handle 34 is moved in one direction, it will move the clutch 10 into engagement and positively separate the clutch members 1G and 17, compressing the springs 46 and 47. When the handle is again brought to the neutral position the clutch 10 is released and the springs return the clutch members 16 and 17 into engagement. When the handle 34 is moved in the other direction,

the clutch member 9 is brought into engage' ment with its pulley and at the same time, through the medium of the frame 24 and the link 29, the levers 37 are acted upon to sever the connection between the clutch members 1G and 17, and which, as in the former case, compresses the springs 46 and 47 As may be seen, by this arrangementthrough the medium of the pulley and belt, a fast traverse movement may be given. It also may be seen that this movement may be given in either direction, and in whichever direction it be given the feeding clutch is out of action and the rapid traverse movement continues only so long as the feeding clutch mechanism is out of action. This arrangement, by means of the belt and the appurtenant mechanism, is very valuable in that it affords a releasing element which will yield before a breaking load is brought on the rapid traverse mechanism.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is 1.
